Multisensor – BHH-320

BH-320 is a multisensor detector based on an optical point smoke detector combined with a temperature sensor.

Principle of Operation

A rise in temperature will change the detection platform by increasing the smoke sensitivity in order to improve the detection of combustion gases from flaming fires producing barely a minimum of visible smoke particles. The multisensor principle combined with advanced signal processing in the detector ensures an early response to any type of fire development. Dual – 2 – sensor detector. Photoelectric, operating on the light scatter principle and temperature measurement by means of a thermistor. SelfVerify: the detector’s ability to initiate alarm is regularly checked.


  • Interactive
  • Ensures fast response to various fire developments
  • Smoke detector for detection of combustion gases mainly consisting of visible (large) particles. Heat sensor assisting for early detection of flaming fires.
  • Additional PCB coating, ideal in humid environments
  • DYFI+ adaptive and self-learning function
  • With SelfVerify function for reduced maintenance/testing and increased reliability
  • Built-in thermistor for reading of temperature at the detector point
  • Short circuit isolator in each detector
  • A built-in alarm indicator (LED)
